Key Take-aways
- 30 000 flight-hours (FH) is the current fleet-leader record on PW127M-powered ATR-42-600.
- PW127 series averages 26 000–28 000 FH between major overhauls in airline service.
- Hot-and-high operations (e.g., India) still achieve > 24 000 FH by using CMAS-resistant HPT blade coating (SB 72-1045).
These figures translate to 10–12 years of typical turboprop duty cycles before the first major shop visit.
